Eukaryote vs prokaryote cells

Two types of Cells: Prokaryote and Eukaryote

Characteristics of Prokaryote cells

Prokaryote cells are small and simple

•Very small, about 3

•Only Single-celled (unicellular) organisms

µm

Prokaryote cells outer layer

• capsule: slimy outer coating

• cell wall: tougher middle layer

• cell membrane: delicate inner skin

• pili: for sticking to things

• flagella: Some have, used to move

• cytoplasm: inner liquid filling

• DNA in one big loop in the cytoplasm

• Ribosomes suspended in cytoplasm

Prokaryote cells have a simple cellular organization:

Types of Prokaryotic Cells

• Bacteria

• Archaea

A cell is Eukaryotic if…it contain a membrane-bound nucleus with

genetic material.

Characteristics of Eukaryotic Cells

• Larger, around 20

• Can be multicellular or unicellular

µm

• Has a plasma membrane surrounding cytoplasm

• Has membrane bound organelles

• Has membrane bound, linear, DNA

Eukaryotic cells characteristics

•Plant

•Animal

•Protists

•Fungi
